Small, developmental inclusion cysts in the newborn infants located on the buccal or lingual aspect of the alveolar ridge (according to the classification by Fromm (1967)) or scattered over the hard palate, near the soft palate junction (according to Bohn, around 1800), believed to be derived from the minor salivary glands. Identical cysts along the median raphe are called Epstein’s pearls, and on the crest of the alveolar ridge, gingival or alveolar cysts of the newborn, originating from the dental lamina (dental lamina cysts).
Bohn’s nodules are present in 65–85% of neonates.
Bohn’s nodules are present in neonates, rarely after 3 months.
No gender predilection.
Small, 1–3 mm, white or yellow–white papules on the hard palate, along the midline, near the soft palate junction or on the buccal or lingual aspect of the alveolar ridge.
Bohn’s nodules are self-healing within a few weeks/months. The small cysts rupture spontaneously and/or fuse with the oral epithelium.
